Sporulation phenotypes of different S. venezuelae strains grown on MYM agar for 7 days at 30°C. 1, NRRL B-65442; 2, NRRL B-902; 3, ATCC 10595; 4, NRRL 2277; 5, ATCC 10712; 6, Sven_Dalhousie; 7, strain 13 s. With the exception of NRRL B-65442 (the JIC strain), the NRRL and ATCC isolates were obtained from the respective culture collections; Sven_Dalhousie (formerly designated ATCC 10712) and strain 13 s (another S. venezuelae isolate used by the Vining laboratory (Ahmed & Vining, 1983)) were kindly provided by David Jakeman from the Vining collection. See the Supplementary material for more information about the origin of the different strains. The original RAW file is available from the authors upon request.
